The Internuclear Ophthalmoplegias

1993

Internuclear ophthalmoplegia (INO), which is caused by an ipsilateral medial longitudinal fasciculus (MLF) lesion, is characterized by adduction paresis of lateral gaze, usually with spared convergence [1–4]. In the opposite eye, abduction nystagmus and hypermetric abduction saccades are the main clinical and electro-oculographic abnormalities [1, 5, 6]. The origin of both is still debated. Abduction nystagmus has been explained by (a) an additional horizontal gaze paresis [7]; (b) vergence mechanisms aimed at alignment of the visual axes [8]; (c) interruption of descending excitatory projections from oculomotor nucleus internuclear neurons to contralateral abducens nucleus motoneurons [9];…

Automatic Conjunctival Provocation Test Using Hough Transform of Extended Canny Edge Maps

2013

Computer-aided diagnosis is developed for assessment of allergic rhinitis/rhinoconjunctivitis measuring the relative redness of sclera under application of allergen solution. The patient’s eye images are taken from commercial digital camera. The iris is robustly localized using a gradient-based Hough circle transform. From the center of the pupil, the region of interest within the sclera is extracted using geometric anatomybased a-priori information. The red color pixels are extracted thresholding in the hue, saturation and value color space. Then, redness is measured by taking mean of saturation projected into zero hue. Evaluation is performed with 92 images taken from 13 subjects, 8 respo…

The functional significance of colour polymorphism in the European common wall lizard (Podarcis muralis)

2021

Colour polymorphisms, the coexistence of two or more colour morphs of a species within a population, have long fascinated evolutionary biologists interested in the mechanisms generating and maintaining phenotypic variation in nature. The functional significance of colour polymorphisms (i.e. their adaptive value) is often linked to the selective mechanisms responsible for their maintenance over time. In lizards, the hypothesis that colour morphs may reflect alternative reproductive strategies involving differential sociosexual behaviour and/or alternative reproductive strategies has come to dominate the field. Wall lizards (family Lacertidae, genus Podarcis), with several geographically dist…

Magnetic stimulation in the definition of eloquent cortical areas

2003

Publisher Summary This chapter discusses the physiological principles of transcranial magnetic stimulation (TMS) and focus on detailing the techniques used in TMS mapping of the motor cortex relating it to the use of TMS in the presurgical assessment of patients with epilepsy. Since the main measure of TMS is the motor potential evoked in muscles, fine delineation of the functional topography of cortex is limited mainly to the primary sensorimotor cortex. In addition, TMS might be helpful to identify language dominance. The characterization of eloquent cortical areas is important in epilepsy surgery for the planning of the resection. TMS is not routinely employed for this purpose and TMS ma…

Genome-wide association study and mouse expression data identify a highly conserved 32 kb intergenic region between WNT3 and WNT9b as possible suscep…

Item does not contain fulltext Bladder exstrophy-epispadias complex (BEEC), the severe end of the urorectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients presenting the most common BEEC form, classic bladder exstrophy (CBE), to identify common variation associated with risk for isolated CBE. We employed discovery and follow-up samples comprising 218 cases/865 controls and 78 trios in total, all of European descent. Our disc…

El turismo, ¿fin de època?. Desafíos de España como destino turístico en un nuevo escenario

2022

La pregunta sobre el fin de época del turismo que se plantea en el título no es una alusión a un cambio de ciclo o de fase, ni tampoco al fin del turismo, sino a la emergencia de un nuevo modelo, una transformación de alcance estructural, tanto de sus factores inductores como de sus manifestaciones multidimensionales en un mundo interrelacionado. Los indicios de esta transición empezaron a intensificarse a lo largo de la última década, antes de la aparición de la COVID-19, cuyos efectos se han sumado a otros factores. Ante la diversidad de los procesos específicos de transformación, el contenido de la obra se ha centrado en el análisis y la valoración de cuatro factores clave que, interrela…

Sostenibilidad en las áreas metropolitanas

2022

Las áreas metropolitanas son, por su complejidad, un atractivo objeto de estudio para científicos sociales de todas las especialidades. El presente libro es producto de dicho interés, y en él confluyen diferentes perspectivas y enfoques provenientes de la Geografía, la Sociología, el Trabajo Social y la Ciencia Política. Concretamente, el origen de este conjunto de estudios sobre los aspectos territoriales, sociales y políticos más relevantes de las áreas metropolitanas es el 'I Congreso Internacional sobre Sostenibilidad Metropolitana', celebrado en Valencia en 2013. Las ponencias invitadas a este congreso son las recogidas en este libro. El origen de dicho congreso es anterior, pues parte…

The Context of Rural–Urban Relationships in Finland, France, Hungary, The Netherlands and Spain

2009

This paper presents a comprehensive view of the empirical research findings concerning rurban relationships in different European countries (Finland, France, Hungary, the Netherlands and Spain), through two types of rurban territories: those that are placed close to (or included in) a metropolitan area and those that are close to (and influenced by) an important tourist area or place. Its main aim is to show the diversity of European experiences with regard to urban pressure in this type of areas, highlighting the socio-economic and institutional contexts in explaining similarities and differences between five countries. The results will review the various meanings of ‘rural’ and ‘rurality’…

Territorial Connection and Cohesion - The Case of Agrigento Inland Area

2014

The Europe 2020 strategy and the Horizon 2020 program can begin a real path about the role that the city will be able play for a new development. Usually, it is in the cities that are intensifying tangible and intangible social relations and, given that they focused almost 70% of the world population, it is clear that the city must begin to start any development scenario: the problems / opportunities related to the management of natural resources, energy to move. The culture is a «primary factor of urban creativity (...), the city's identity that has its roots the program schedule of history and extends its branches in the future» [4], awaiting a new model of development local self-sustaina…
